METHOD FOR DETERMINING THE AMOUNT OF THE ADDITIVE “AGIDOL-1” IN DIESEL FUELS Russian patent published in 2021 - IPC G01N33/22 

FIELD: diesel fuels.

SUBSTANCE: invention is used to determine the amount of the additive "Agidol-1" in diesel fuels. The essence of the invention lies in the fact that a sample is taken, chromatographic separation is carried out on a Kromasil 100-3.5 C-18 column having a length of 100 mm and a diameter of 3.5 mm, UV detection at a wavelength of 210 nm, identification of the peak corresponding to the component "Agidol-1", the subsequent determination of the peak area and plotted in the coordinates of the area of the peak - the concentration of the additive to the calibration graph, finding the amount of the additive "Agidol-1", while before chromatographic separation, a sample of diesel fuel is mixed with isopropyl alcohol in a ratio of 1: 9.

EFFECT: invention is aimed at expanding the range of methods for determining the Agidol-1 additive in fuels with a viscosity of up to 4,000 mm2 / s using high-performance liquid chromatography with a simultaneous reduction in the analysis time to no more than 60 minutes, as well as eliminating the use of toxic substances.
